How to develop biofilms buried sewage treatment equipment? A sewage into the device; 2, start the fan, sludge pumps, oxygenation amount reduced to about half the normal fan oxygenation amount; 3, to observe a day of aerobic tanks packing cases, such as on a long orange or orange packing a layer of sticky black substance, already cultivate good biofilm cultured period generally 10--25 days to complete; 4 Celsius temperatures generally at 15 ℃ - 25 ℃ most appropriate; 5, if the concentration is too low raw sewage wastewater treatment cultivate biofilms too long, if necessary, to add a little nutrition, mainly in faeces mainly or other; 6, PH value must ensure that at 6.5 - 8.5 between rural sewage treatment, raw sewage can reach to ensure that the biochemical status; 7, treatment of industrial waste water and hospital sewage, sewage mainly want to start debugging before, good to be cultured biofilms, small amounts of other industrial waste water continuously into the sewage treatment process, so that the growth of the biofilm adapt industrial sewage that normally start debugging .

The role of the three sewage treatment equipment together Shanxi Environmental Engineering Limited in the role of craft beer wastewater sewage treatment equipment in the beer Wastewater from the fine grid initial solid-liquid separation, it is not primary sedimentation tank; acidification pool located fillers, for bacteria to provide a three-dimensional shape of the bio-bed, the particulate matter and water retention and adsorption of colloidal substances, while under the effect of hydrolysis bacteria, dissolved organic matter will not be hydrolyzed to soluble substances, acid-producing bacteria in synergy, the The macromolecular substance, substance is difficult biodegradable small molecules into a readily biodegradable. Reason materialized dosing method chosen reaction flotation tank mainly three points: First, the removal of suspended solids, such as high, normal sedimentation tank removal is only about 30%, vertical flow sedimentation tank is 40% to 50%, while gas float up to 80% to 90%; the second is flotation sludge moisture content of 97% to 98%, can be directly slag flotation dehydration, while the other settling tank sludge moisture rate of more than 99%; the third is flotation tank flotation short hydraulic retention time of sewage treatment equipment prices, about 30min, while other sedimentation tank HRT 1.5 ~ 2h, so small flotation cell volume, reducing the footprint. However, the addition of a flotation process requires air compressors, pressure dissolved gas cylinders, pumps and other components reflux auxiliary systems, operations management is relatively complicated.
